Abstract (en)

[origin: EP3842989A1] Provided is a method, performed by an electronic device, of reading a barcode, the method including obtaining an image by capturing an image of the barcode, determining a plurality of lines that cover a part of the barcode from the image, obtaining information about a distortion level of the barcode in a region adjacent to each of the plurality of lines, determining at least one line for reading the barcode from among the plurality of lines, based on the obtained information, and reading the barcode based on the determined at least one line.
